Well, usually the way it works is:
Your name is called out & the amount of weight you have lost to date. That gets a clap. Then she says whether you have lost or gained, she asks what kind of week we had & if we have gained she asks what we might have done dofferently this week compared to the weeks we have lost weight. If we have a big gain & no explanation she asks us to leave her our food diaries & she will call us during the week for a chat. TBH she calls during the week most weeks, she's really supportive.
The fruit goes to slimmer of the week. That is the person who has the most weight off, but has also lost the week before. ie: last night I had lost 4lb, the most in the group, but because I had gained weight last week it didn't go to me [I am sure there are other reason why people get SOTW, that's just one of the reasons I know]
The raffle is usually for a good prize, a set of scales to weigh food, some items for a particular recipe, or a sw recipe book etc...
Other people chat & give us their favourite recipes & every now & again we all bring in something from our fave recipes. Eg: Last night was our consultants year anniversary of beginning the class in our area, so we all made bits & took them in, fruit kebabs, chicken curry etc..all made to sw recipes.
Are you sure that the things people are eating in class aren't the bars they sell there? [Can't remember their name] And the crisps may have been ryvita minis?? They are sold at our sw classes???
